简介
远程 Oracle Linux 主机缺少一个或多个安全更新。描述
远程 Oracle Linux 8 主机上安装的程序包受到 ELSA-2023-12195 公告中提及的多个漏洞的影响。- 在 QEMU 中对 VMWare 的半虚拟化 RDMA 设备的实现中发现一个缺陷。此缺陷允许特制的客户机驱动程序在尚未分配共享缓冲区时执行硬件命令，从而可能导致释放后使用情况。 (CVE-2022-1050)
- 在 QEMU 的 ACPI 错误记录序列化表 (ERST) 设备中，在 read_erst_record() 和 write_erst_record() 函数中发现整数溢出和缓冲区溢出问题。这两个问题都可能允许客户机溢出为 ERST 内存设备分配的主机缓冲区。恶意客户机可利用这些缺陷造成主机上的 QEMU 进程崩溃。(CVE-2022-4172)
- 在 QEMU 的 QXL 显示设备仿真中发现一个越界读取缺陷。qxl_phys2virt() 函数不检查客户机物理地址指向的结构的大小，因此可能将超出条形空间的末尾读入邻近页面。恶意访客用户可利用此缺陷造成主机上的 QEMU 进程崩溃，从而导致拒绝服务情形。(CVE-2022-4144)
- 处理扩展格式的 ClientCutText 消息时，在 QEMU VNC 服务器中发现整数下溢问题。恶意客户端可利用此缺陷，通过发送特制的负载消息来造成 QEMU 无响应，从而导致拒绝服务。(CVE-2022-3165)
请注意，Nessus 尚未测试这些问题，而是只依据应用程序自我报告的版本号进行判断。
